Tenille Townes, Oklahoma country group Turnpike Troubadours and the Steel Woods will all serve as opening acts throughout the trek, which begins July 12 in Charlotte, N.C., and continues through August. The tour will also include esteemed Nashville songwriter Natalie Hemby, a gifted vocalist herself who's behind some of Lambert and Little Big Town's biggest hits including "White Liar," "Baggage Claim" and "Pontoon."

Townes is set as an opening act for all dates, while the Turnpike Troubadours join for the bulk of the tour. Hemby will open the first three nights, with the Steel Woods hopping on for both dates in Texas. Three additional dates have been announced for Houston on Aug. 10, Dallas on Aug. 11 and Chicago, where the tour will wrap up on Aug. 25.

The superstar acts announced the first round of tour dates in early January, making stops in Indianapolis, Tampa, Philadelphia, Toronto, Canada and more throughout the summer months. Both Lambert and LBT are currently on the road on their individual tours before uniting for the co-headlining trek, with Lambert helming the Livin' Like Hippies Tour through March while the "Girl Crush" singers tour the country with Kacey Musgraves and Midland on the Breakers Tour until mid-April.

Lambert and LBT are nominated in multiple categories at the 2018 ACM Awards, with Lambert scoring nods for Song of the Year for "Tin Man," Female Vocalist of the Year and Video of the Year for "We Should Be Friends," while the quartet holds down the fort in the categories of Vocal Group of the Year, Album of the Year for The Breaker and Single Record of the Year for "Better Man." The awards air live from Las Vegas on April 15.
